[0002] One of the steps in the preparation process of plastic particles is to stir and mix the required plastic masterbatch in a mixing tank and then heat and melt it to obtain plastic particles of corresponding specifications. However, in the actual stirring process, plastic particles often have static electricity. Even if a metal tank body and stirring blades are used, static electricity still exists between plastic particles, affecting the subsequent mixing effect. The existing process mainly uses methods such as adding anti-static agents or increasing humidity in the mixing tank, blowing plasma wind, etc. to eliminate static electricity. However, the former is more expensive, and the latter is ineffective due to excessive stacking of plastic particles in the mixing tank.

[0026] like Figure 1-5 As shown:

[0027] A plastic granule production device includes an outer shell 000, an inner shell 010 is connected to the inner side of the outer shell 000 by screws, an outer rotating rod 020 is welded to the inner side of the inner shell 010, an inner rotating rod 030 is rotatably connected to the inner side of the outer rotating rod 020 through an arc-shaped slide groove, the inner rotating rod 030 is welded to the inner shell 010, a stirring part 100 that can be driven to rotate by a rotating motor is installed on the outer side of the outer rotating rod 020, a control box 040 is connected to the lower side of the inner shell 010 by screws, and the rotating motor is arranged on the control box 040. The inside of the box 040 is connected to the stirring part 100 through gears, the lower side of the outer shell 000 is connected to the water tank 050 by threads, the inner side of the water tank 050 is connected to the electric telescopic rod 210 by screws, and multiple cleaning parts 220 are hinged on the electric telescopic rod 210, and the multiple cleaning parts 220 are fixed to the electric telescopic rod 210 by springs, and the inner shell 010, the outer rotating rod 020, the inner rotating rod 030 and the stirring part 100 are all provided with through grooves 001 corresponding to the cleaning parts 220;

[0028] Before the production equipment is put into use, the water tank 050 can be opened, clean water can be filled into the water tank 050, and then the water tank 050 can be installed on the lower side of the outer shell 000 to complete the preparation work before the production of plastic particles. Then, the various plastic masterbatches to be mixed can be poured into the inner shell 010 in sequence, and then the rotating motor can be started, and the stirring part 100 can be driven by the rotating motor and the gear to start, and then the plastic masterbatches in the outer shell 000 can be mixed by the stirring part 100, so that the plastic masterbatches can be evenly mixed, which provides convenience for the subsequent melting processing; during the mixing process, the rotating motor can be turned off, and then the electric telescopic rod 210 can be controlled to extend, so that the electric telescopic rod 210 drives the cleaning part 2 20 moves upward from the inner side of the inner rotating rod 030 until the cleaning part 220 is completely moved out from the inner rotating rod 030 and unfolded under the action of the spring tension, and then the electric telescopic rod 210 can be controlled to shorten, so that the electric telescopic rod 210 can drive the unfolded cleaning part 220 to descend. During the descent, the cleaning part 220 can be opened, so that the cleaning part 220 can expand the contact area with the plastic masterbatch, until the cleaning part 220 passes through the inner shell 010 and falls into the water tank 050, so that the static electricity generated by the friction between the plastic masterbatch can be eliminated through the contact between the cleaning part 220 and the plastic masterbatch, and then the rotating motor can be started again, and the above operation is repeated until the mixing of the plastic masterbatch is completed;

[0029] Furthermore, during the mixing process, after the cleaning part 220 falls into the water tank 050, the cleaning part 220 can be immersed in the clean water in the water tank 050 to moisten the cleaning part 220, so that the static electricity between the plastic masterbatch can be eliminated by the clean water on the cleaning part 220, thereby completing the static electricity elimination work. At the same time, since the cleaning part 220 needs to follow the electric telescopic rod 210 to pass through the inner rotating rod 030 during the rising process, the inner rotating rod 030 and the outer rotating rod 020 can squeeze the cleaning part 220 at this time, so that the excess water attached to the cleaning part 220 can be squeezed out and fall back into the water tank 050, so that it can be ensured that the cleaning part 220 will not be attached with too much water after it is unfolded, which will affect the subsequent melting process;

[0030] Secondly, the setting of the through groove 001 can ensure that the cleaning part 220 can smoothly pass through the plastic masterbatch from top to bottom, and will not be deformed or displaced under the interference of the plastic masterbatch, resulting in the situation that it cannot accurately pass through the inner shell 010 and enter the inside of the water tank 050;

[0031] At the same time, the outer rotating rod 020 and the inner rotating rod 030 that can rotate relative to each other can be combined into a closed circular tube through rotation, thereby preventing the cleaning part 220 from popping out through the through groove 001 during the ascending process.

[0032] like Figure 8 As shown:

[0033] The stirring part 100 includes a lower turntable 110, an upper turntable 120 is arranged on the upper side of the lower turntable 110, and a plurality of guide rods 130 and stirring blades 150 are arranged between the lower turntable 110 and the upper turntable 120. The plurality of stirring blades 150 are all bonded to the corresponding outer sides of the lower turntable 110 and the upper turntable 120. The two ends of the plurality of guide rods 130 are respectively fixed to the lower turntable 110 and the upper turntable 120 through universal ball joints. The lower side of the upper turntable 120 is also connected with a plurality of support rods 140 by threads. The plurality of support rods 140 are all arranged on the outer sides of the corresponding guide rods 130. The upper turntable 120 is slidably connected to the outer turntable 020 through a longitudinal slide groove. The lower side of the lower turntable 110 is rotatably connected to the inner shell 010. The water tank 050 is composed of a plurality of cross bars hinged in parallel and can be bent longitudinally.

[0034] When the rotating motor is started, the output shaft of the rotating motor drives the lower turntable 110 to rotate through the gear. Since the upper turntable 120 is slidably connected to the outer turn rod 020 through the longitudinal slide groove, the outer turn rod 020 can only slide up and down on the outer turn rod 020, but cannot rotate on the outer turn rod 020, so that the lower turntable 110 can generate relative rotation with the upper turntable 120 during the rotation process. At this time, the upper turntable 120 can move downward under the pulling action of the guide rod 130 until the lower end of the support rod 140 contacts the upper side of the lower turntable 110, so that the lower turntable 110 and the upper turntable 120 cannot continue to approach each other, and then the rotation of the lower turntable 110 can drive the upper turntable 120 and the outer turn rod 020 to rotate on the inner turn rod 030, and then the plastic masterbatch can be stirred through the inclined water tank 050 to complete the mixing work;

[0035] When the cleaning part 220 needs to be lowered, the rotating motor can be stopped first, so that the cleaning part 220 can be inserted into the through grooves 001 on the outer rotating rod 020 and the inner rotating rod 030, so that the outer rotating rod 020 can not continue to rotate on the inner rotating rod 030, and then the rotating motor can be rotated in the reverse direction to make the lower turntable 110 rotate in the reverse direction until the guide rod 130 and the stirring blade 150 are completely vertical. At this time, the upper turntable 120 can slide adaptively on the outer rotating rod 020 to avoid the situation that the upper turntable 120 cannot move up and the guide rod 130 cannot be reset. At this time, the cleaning part 220 can smoothly pass through the stirring part 100 and the inner shell 010 into the water tank 050 without interfering with the inclined stirring blade 150.

[0036] The setting of the universal ball joint enables the guide rod 130 to rotate freely on the lower turntable 110 and the upper turntable 120, thereby preventing the lower turntable 110 from getting stuck with the guide rod 130 during rotation;

[0037] The inclination angle of the stirring blade 150 can be changed by adjusting the length of the support rod 140 to achieve a corresponding stirring effect for plastic masterbatches of different quantities and sizes.

[0038] like Figure 6 , 9 As shown:

[0039] The water tanks 050 are provided with three, and rotating motors and output gears are provided inside the three water tanks 050. The three output gears are respectively meshed with the outer rotating rod 020, the inner rotating rod 030 and the lower side of the lower turntable 110, and the inner rotating rod 030 is rotatably connected to the outer shell 000, so that the outer rotating rod 020, the inner rotating rod 030 and the lower turntable 110 can be controlled and adjusted respectively by the three rotating motors to ensure that when the cleaning part 220 moves downward, the through grooves 001 on the outer rotating rod 020 and the stirring part 100 can be aligned with the through grooves 001 on the inner shell 010, and at the same time, the inner rotating rod 030 can be adjusted to avoid displacement during long-term use.

[0040] like Figure 5 As shown:

[0041] The cleaning parts 220 all include a lower slide 230, which is arranged on the upper side of the electric telescopic rod 210, one end of the lower slide 230 is hinged on the electric telescopic rod 210, the inner side of the lower slide 230 is connected to the top of the electric telescopic rod 210 through a spring, an absorbent sheet 240 is bonded to the upper side of the lower slide 230, and an upper slide 250 is bonded to the upper side of the absorbent sheet 240. When the cleaning part 220 is placed horizontally, the two ends of the absorbent sheet 240 are in contact with the inner wall of the inner shell 010 and the outer wall of the outer rotating rod 020 respectively, and the width of the absorbent sheet 240 is greater than that of the lower slide 230 and the upper slide 250, and the width of the lower slide 230 and the upper slide 250 is the same as the width of the through groove 001;

[0042] When the cleaning part 220 moves upward along with the electric telescopic rod 210, the cleaning part 220 is pushed inward by the inner rotating rod 030, so that the spring is stretched and deformed. At this time, since the upper slide bar 250 is arranged on the upper side of the cleaning part 220, the upper slide bar 250 can contact the inner rotating rod 030 first, thereby preventing the spring fixed to the lower slide bar 230 from getting stuck when contacting the inner rotating rod 030.

[0043] At the same time, when the cleaning part 220 follows the electric telescopic rod 210 to descend, the outer side of the upper slide bar 250 can be inserted into the through groove 001 on the inner shell 010, and the inner side of the lower slide bar 230 can be inserted into the through groove 001 on the outer rotating rod 020 and the inner rotating rod 030, so that the water-absorbing sheet 240 can be stuck between the outer rotating rod 020 and the inner shell 010, so that the water-absorbing sheet 240 can stably slide downward between the plastic masterbatches. At the same time, due to the friction between the accumulated plastic masterbatches, the water-absorbing sheet 240 can be unfolded, thereby ensuring that the water-absorbing sheet 240 can contact as many plastic masterbatches as possible, thereby improving the static electricity elimination efficiency.

[0044] like Figure 4 As shown:

[0045] The inner shell 010 is provided with an inclined surface on its upper side, so that the cleaning portion 220 can be positioned through the inclined surface, so that the upper slide bar 250 can smoothly slide into the through groove 001 on the inner shell 010 .

[0046] Further:

[0047] Sealing gaskets are provided at both ends of the through groove 001, so that the through groove 001 can be sealed by the sealing gasket to prevent smaller plastic masterbatch from slipping out of the through groove 001 and causing clogging of the mixing equipment. At the same time, the sealing gasket can make the two sides of 010 fit together when the cleaning part 220 has not entered the through groove 001, and then during the rotation of the outer rotating rod 020, the entire outer rotating rod 020, the inner rotating rod 030 or the stirring part 100 can be driven to rotate only by the gear moving one side of the outer rotating rod 020, the inner rotating rod 030 or the stirring part 100.

[0048] like Figure 5 , 7 As shown:

[0049] A soft stop cover 260 is welded on the upper side of the electric telescopic rod 210. The soft stop cover 260 is made of a deformable material, and the diameter of the soft stop cover 260 is larger than the inner diameter of the inner rotating rod 030; therefore, when the electric telescopic rod 210 is inserted into the inner rotating rod 030 and extends, driving the cleaning part 220 to move upward, the soft stop cover 260 can cover the spring on the inner side of the lower slide bar 230, and at the same time provide guidance for the upper slide bar 250, further ensuring that the upper slide bar 250 can slide smoothly into the inner rotating rod 030, avoiding jamming between the upper slide bar 250 and the inner rotating rod 030.

[0050] Further:

[0051] The lower slide bar 230 is a deformable metal soft film, and the upper slide bar 250 is a thin metal rod, so that the lower slide bar 230 can pass through the plastic master batches by deformation during the downward movement, thereby preventing the plastic master batches located directly below the lower slide bar 230 from interfering with the cleaning part 220. At the same time, the provision of the thin metal rod can prevent the upper slide bar 250 from sliding out of the groove 001 on the inner shell 010 due to excessive deformation, resulting in the cleaning part 220 being unable to fall into the water tank 050 normally.

[0052] Further:

[0053] The inner side of the spring is provided with a compression support rod with one end free and the other end hinged on the electric telescopic rod 210, so that the downward sliding bar 230 can be supported by the compression support rod to avoid the situation in which the downward sliding bar 230 is unable to pass through the plastic masterbatch due to reverse deformation during the downward sliding of the cleaning part 220.

[0054] A method for producing plastic particles, the method comprising the following steps:

[0055] a: Pour the prepared plastic masterbatch into the inner shell 010 in sequence, and fill water into the water tank 050;

[0056] b: Start the control box 040, and control the stirring part 100 to stir the plastic masterbatch through the control box 040;

[0057] c: When it is necessary to remove static electricity from the plastic masterbatch, close the control box 040, control the electric telescopic rod 210 to drive the cleaning part 220 to extend from the inside of the inner rotating rod 030;

[0058] d: When the cleaning part 220 is completely extended from the inner rotating rod 030 and unfolded, the electric telescopic rod 210 is controlled to drive the cleaning part 220 to descend;

[0059] e: After the cleaning unit 220 descends into the water tank 050, the control box 040 is started to repeat the stirring work of the stirring unit 100 on the plastic masterbatch;

[0060] f: Repeat steps ce until the mixing of the plastic particles is completed.
